AMIS0441 Au 2.44 g/t Greenstone Taylor South Africa

Origin of Material: The material for AMIS0441 was provided by Vantage Goldfields from Taylors Mine section of the Barbrook Mine. Barbrook is located 25 kilometres east north east of the town of Barberton in Mpumalanga Province, South Africa. The mine is situated in the Archaean Barberton Greenstone Belt. Gold is contained in mesothermal veins associated with late tectonic shears and fractures within rocks of the Barberton Supergroup, which comprises an assortment of ultramafic and mafic submarine volcanics, turbiditic greywacke sandstones and shales. Intense shearing, massive quartz veining, silicification of BIF and sulphide enrichment characterize the larger ore bodies. In the Barbrook area shearing has been focused along two lines, the Barbrook and Zwartkoppie.

Approximate Mineral and Chemical Composition: The Taylors ore body is on the Barbrook line and comprises 900 metres of disjointed orebodies aligned along E-W trending shear zones within a BIF unit. The BIF is bounded by greywacke’s. Gold-bearing fluids migrated along major feeder fractures into zones where fluid reaction with the iron-rich host rock resulted in sulphide mineralization and gold precipitation. Gold is associated with disseminated pyrite, pyrhotite and arsenopyrite, and to lesser extent base metal sulphides.
